I have the K2s and I like 'em. Love my Pure Grits. . . so I'm leaning toward trying the Flows or Connects. . . but, I'm really curious about the K3s. . . Too bad I can't just buy them all, which I probably will at some point anyways.

I'm tossing up the idea of the Connects or the Flows. . . possibly as a marathon shoe. The extra cushion of the Flow might be nice, but the Connects seem more like my Kinvara. Hmmm. . . anyone want to buy me all of 'em? It WAS my b-day yesterday. . .

Well, Angie, my shoe-twin... I have the Pure Flow so you need to get it too! hehehe!! I do love the cushioning! So soft and yet so lightweight and flexible! Have not run in any Kinvaras, but have tried them on and like 'em!
